- Context (TH | DTE): SC criticised the Genetic Engineering Appraisal Committee (GEAC) for not considering the recommendations of the Technical Advisory Committee report (TEC).
Background
- The GE mustard was developed in the 1990s and patented in 2002 by CGMCP. (The Centre for Genetic Manipulation of Crop Plants, University of Delhi).
- it was developed using barnase, barnstar, and bar genes.
Near approval of GM Mustard in 2017
- In September 2015, CGMCP submitted an application to the GEAC requesting permission for the environmental release of DMH-11.
- In 2016, GEAC constituted a Sub-Committee to review the technical details and Dossier.
- The Sub-Committee submitted in its final report, “Assessment of Food and Environmental Safety (AFES)”, approved for the environmental release.
- It concluded that the hybrid DMH-11 does not pose any risk of causing any adverse effects on human and animal health and safety.
- In May 2017, GEAC recommended environmental release of GE Mustard for approval by MoEFCC.
- However, the approval was not given by MoEFCC due to the pressure from activists, scientists, etc.
How did the issue resurface?
- On October 18, 2022, the MoEFCC approved the environmental release of GM mustard.
- In November 2022, the SC issued a status quo. Since A group of petitioners challenged the decision. (activist Aruna Rodrigues, NGO Gene Campaign, etc.)
- They seek a moratorium on releasing any GMOs until independent expert bodies conduct a comprehensive bio-safety protocol in the public domain.
Earlier Committee reports have called for a ban on GMOs

India and GM crops
- In 2004, India allowed commercial cultivation of GM cotton (non-edible), which now accounts for more than 90% of the nation’s harvest.
- In 2010, GM eggplant (brinjal) also cleared GEAC’s review, but an indefinite moratorium was placed on its introduction, citing safety concerns.
- Dhara Mustard Hybrid-11 (DMH-11) will be the second GM plant, and the first Indigenously developed GM food crop to reach India’s farmers (if approved).

Why hybrids are needed?
- Crossing of genetically diverse parents results in hybrids with increased yield (20-25 per cent) and adaptation. This phenomenon is known as hybrid vigourorheterosis.
- It has been widely exploited in crops like rice, maize, pearl millet, sunflower and many vegetables.
Government’s argument
- Economic security: Hybrids yield higher than pure-line varieties and will help the country reduce its edible oil deficit.
- India faces a severe shortage of edible oils. Imports of over 14 million tonnes (around Rs 1.5 lakh crore) in foreign exchange in 2021-22.
- The government claims that transgenic seeds could raise yields to 3-3.5 tonnes per hectare while resistant to pests that cause white rust.

- Food Security: Given the increased growth of the Indian population and urbanisation, GM crops offer promising solutions to meet the world’s food security needs.
- Safety: Several international organisations (FAO, WHO, OECD) have concluded that biotechnology products are as safe and nutritious.
- Use of technology: A major challenge today is to develop low-input, high-output agriculture. This cannot be achieved without technology.
Concerns against GM Crops
- Threatens the future of apiculture export: Mustard honey crystallises quickly, making export to the US and EU feasible. But these countries also demand GM-free certification.
- No increase in Yield: The highest yields in mustard are from the five countries that do not grow GM mustard (U.K., France, Poland, Germany and the Czech Republic) and not from the GM-growing U.S. or Canada (FAO data).
- Issue of Resistance: Besides White Rust, the mustard crop is also prone to other diseases. The pests and insects may grow resistant to the transgenic crop after a decade.
- Undesirable consequences
- Honeybees could transfer the genes of GM mustard to other plants, which may lead to the growth of unwanted and invasive weeds.
- Transgenic technology, unlike other technologies, is uncontrollable and irreversible after environmental release.
- There are also no long-term studies in the Indian context on the metabolic impact of barstar and barnase genes on the human and animal body.
- Regulatory violations: Civil society groups have put out detailed evidence-based reports to showcase several illegalities concerning regulatory appraisal.
- For example, the full biosafety dossier of GM mustard has not been published on the regulator’s website.
- There has been no health expert involved in GM mustard safety appraisal.
- Explicit objections from numerous states were ignored even though agriculture and health are state subjects per the IC.
- Failure of Bt cotton: There was a proposed link between the poor performance of Bt cotton and many farmers’ suicides, particularly in 2004.
- Issues in classifying GM mustard as a herbicide-tolerant (HT) crop: The government argues it is not a herbicide-tolerant (HT) crop. However, GM mustard is an HT crop because it can withstand herbicides due to the presence of bar genes.
